How to Keep Your HVAC Manufacturer Warranty Valid

How to Keep Your HVAC Manufacturer Warranty Valid starts with understanding one critical fact: most HVAC manufacturers require documented annual professional maintenance to keep your warranty active — and failure to comply is one of the leading reasons warranty claims are denied.

The Hidden Dangers of Clogged Dryer Vents in Fall

When fall arrives in Chicagoland, most homeowners shift their focus to furnaces, fireplaces, and keeping the house warm. But there’s another appliance that deserves attention this season—your clothes dryer. As temperatures drop and outdoor activities slow down, laundry loads tend to increase.

What Your Neighbors Are Saying

NextGen is great!

They helped me install all new appliances in my condo (water heater, furnace, and AC unit). Jason was exceptional as well as his team. During the first site visit, Jason sent me a detailed outline of each item, labor costs, and communicated frequently to address all of my questions - even educate me. I highly recommend NextGen Mechanical for your residential appliance needs.

Very responsive

What a great experience. I had NextGen come over for fall cleaning and Jason took a look at our boiler and unique heating system. We have had multiple companies (large and small) walk through and tell me we were fine, but he was able to diagnose and properly propose a solution for the heating of my basement as well! Very responsive, very professional, and highly-skilled. I will be recommending NextGen to all my friends and family.

I highly recommend Jason and NexGen Mechanical

Jason did a great job repairing my furnace. He came out and found multiple problems with my furnace. He ordered the parts and made the repairs within a couple days at a very fair price.
